# ImageEffect

ImageEffect[image, "effect"]
applies the specified image effect to image.

ImageEffect[image, {"effect", params}]
uses parameters params.

## DetailsDetails

• Available artistic image effects include:
•  {"Charcoal",x} charcoal sketch effect {"Embossing",x,} embossing by an amount x at an angle {"OilPainting",x} artistic oil painting effect {"Posterization",n} posterization effect using n levels in each channel {"Solarization",t} solarization or Sabatier effect {"MotionBlur",d,} motion blur of size d and angle , given in radians
• Pseudo-random noise effects:
•  {"Noise",a} adds zero-mean uniform noise of amplitude a/2 {"GaussianNoise",} adds zero-mean Gaussian noise with standard deviation {"SaltPepperNoise",f} adds salt-and-pepper noise to a fraction f of the image {"PoissonNoise",a} adds an amount a of Poisson noise
• In each case, can be used instead of , and uses default values for parameters.
• can be used to retrieve a list of all available image effects.
• When using , the noise scale is defined as and each pixel value p is replaced with PoissonDistribution[p×]/.
• ImageEffect returns a grayscale image for single-channel images. All other images are converted to RGB.
